In last May I found an elephant remain at the cited locality in a Pleistocene deposit of 15 to 20 m in thickness which consists chiefly of clay, sand and gravel in alternation with intercalations of lenses of andesitic purmice., It is overlain by a younger formation and underlain by the Tertiary agglomerate., The fossil is a fragmentary tooth which may be referred to Palaeoloxodon namadicus naumanni (MAKIYAMA)., The specimen in which three chirolites are preserved is 48 mm long, 73 mm broad and 85 mm high., The grinding surface is concave., On a side of the chirolites there is a distinct loxodont plica at the middle., The enamel layers measure 2 to 2., 5 mm in thickness.,
